AB  - Two-dimensional (2D) COFs have been successfully applied for various 
      applications, such as capillary electrochromatography (CEC). Compared with 2D 
      COFs, three-dimensional (3D) COFs have higher surface area and lower density, 
      which should have superior potential as the separation medium in CEC. However, 
      the 3D COFs on the inner wall of capillary is hard to fabricate in situ. Up to 
      date, the application of 3D COFs in open-tubular capillary electrochromatography 
      (OT-CEC) is still considered a challenge. For the first time the COF-300-coated 
      capillary was prepared by in situ growth (COF-300 was made from 
      terephthalaldehyde and tetra-(4-anilyl)-methane) on OT-CEC. Benzene, 
      methylbenzene, styrene, ethylbenzene, naphthalene, 1-methylnaphthalene, and 
      propylbenzene were used to evaluate the performance of the COF-300-coated 
      capillary by OT-CEC. For three consecutive runs, the intraday relative standard 
      deviations (RSDs) of migration time and peak areas were 0.1-0.4% and 2.5-8.3%, 
      respectively. The interday RSDs of migration time and peak areas were 0.2-0.5% 
      and 1.0-10.8%, respectively. Five groups of aromatic co mpounds were used to 
      further study the separation mechanism, which indicated that hydrophobic 
      interaction and size selection interaction are the main factors. It should be 
      noted that the COF-300-coated capillary can be used for more than 140 runs with 
      no observable changes of the separation efficiency. Graphical abstract The 3D 
      COF-300-coated capillary was prepared by in situ growth for OT-CEC. Six groups of 
      aromatic compounds were separated by 3D COF-300-coated capillary. Size selection 
      and hydrophobic interaction affect the migration time of analytes.
